2) Call pci_restore_state() at beginning of tg3_resume() as
   this helps some chips come out of D3 more cleanly.

- Modify fs/ntfs/ntfs_readdir() to copy the index root attribute value
  to a buffer so that we can put the search context and unmap the mft
  record before calling the filldir() callback.  We need to do this
  because of NFSd which calls ->lookup() from its filldir callback()
  and this causes NTFS to deadlock as ntfs_lookup() maps the mft record
  of the directory and since ntfs_readdir() has got it mapped already
  ntfs_lookup() deadlocks.

This bug took forever to debug (just ask Ben :-).

When we move the completion event from the failed request to the sense
request, we risk either the initial complete and then later complete on
a long gone ->waiting.  I think this business of moving the completion
structure to the request sense is a bit bogus and always has been, and
the bug is fixed nicely by just rewriting this logic a bit.  So instead
we simply unconditionally dequeue the failed request (regardless of
whether it was REQ_PC or REQ_BLOCK_PC), and pass a reference to it in
the sense request.  When the sense completes, we call end io on the
originally failed request (which does the complete() etc).

dup_mmap() unnecessarily tries to account for memory of the vma's it has
created if it fails in the middle.

However, that's pointless (and wrong), since the exit_mmap() path called
through mmput() will do so anyway in the failure path.

Just remove the bogus un-accounting code.

The recent change to vga16fb's memory mapping that you partially reverted
is still broken.  In particular, it's setting fix.mem_start to a virtual
address on i386.  The value of fix.mem_start is meant to be physical.

We could simply apply virt_to_phys to it, but somehow I doubt that is what
it's meant to do on arm.  So until we hear from someone who knows how it
works on arm, let's just revert this change.

The sysctl interfaces for updating the uts entries such as hostname and
domainname are using the wrong length for these buffers; they are hard
coded to 64.  Although safe, this artifically limits the size of these
fields to one less than the true maximum.  This generates an inconsistency
between the various methods of update for these fields.

In testing for SLES9, we ran across a bug caused by userspace apps poking
the PIT which caused bad values to be read by the kernel.  This would then
trigger the lost tick detection code with insane values and would then
break the SCSI subsystem.

This patch includes the PIT sanity check from the TSC timesource into the
cyclone timesource code, which catches the bad case described above and
resolves the issue.

This patch adds support for 6 system call arguments on s390.  The first
exploiter of this will be the sys_futex system call for the
FUTEX_CMP_REQUEUE operation.  The idea is simple: use register %r7 for the
6th argument.  This can be extended to 7/8/9/...  arguments if there ever
will be the need for it.  To call the system call function in the kernel
the additional arguments needs to get stored on the stack.  8 bytes are
added to the head of struct pt_regs.  %r7 is stored to the additional field
for all system calls.  The store is hidden in a
address-generation-interlock slot, it doesn't slow down the system call
path.
